Introduction / Why This Is Needed
System Integrity Protection (SIP), also known as "rootless," is a fundamental security mechanism in macOS, introduced starting with OS X El Capitan. It protects critical system files, folders, and processes from any modifications, even from a user with administrator (root) privileges.
Enabling SIP significantly increases your system's resilience against:
- Malware attempting to inject its components into system directories.
- Accidental or intentional corruption of the kernel and system libraries.
- Attacks that leverage privilege escalation.
This guide will walk you through the process of activating SIP from scratch, from booting into Recovery Mode to verifying the status. The process is safe and fully reversible.
Prerequisites / Preparation
Before you begin, ensure that:
- You have physical access to the Mac (not remote management).
- You know the password for an administrator account (may be required for some operations in Recovery Mode).
- Your Mac has a supported version of macOS installed (Ventura, Sonoma, Sequoia, or newer).
- You have closed all applications and saved any unsaved work, as the process will require a restart.
- Important: If you previously disabled SIP to install certain software (e.g., a system driver or a legacy utility), make sure that software is no longer required, or be prepared to disable SIP again after enabling it.
Step-by-Step Instructions
Step 1: Restart Your Mac into Recovery Mode
Recovery Mode is a special utility environment that allows you to perform administrative tasks unavailable during normal system operation, including managing SIP.
For Mac with Apple Silicon (M1, M2, M3):
- Shut down your Mac via the Apple menu → "Shut Down."
- Press and hold the power button until the startup screen with the text "Loading options" appears.
- Click "Options" and then "Continue."
- Wait for the system to boot into the recovery environment.
For Mac with Intel processor:
- Shut down your Mac.
- Turn on your Mac and immediately hold the key combination
Command (⌘) + R. - Hold the keys until you
